This term was made obsolete because the meaning of the term is ambiguous, as it's possibly conflating at least two scenarios: 1) the organism apoptoses its own cell because it detects it is infected with a virus; 2) the virus induces apoptosis so the cell is lysed and the virus disseminated. Please consider using viral process terms to annotate viral proteins. As for the cellular apoptotic process, this likely occurs via the same mechanisms described by existing apoptotic process terms, so please consider using those to annotate cellular proteins.
